Improved reset for cache. Disabled l2 cache as it currently reduces performance. Added more CCache instructions to code, although likely not needed. Still instability issues when L1I cache is enabled.

Added L1I cache. Added clear cache instruction, which is now added in the UART bootloader and BDOS program loaders. Fixed too fast read part in SPI flasher. Snake userbdos program now sometimes crashes, which needs further investigation.
